Answer:
Step-by-step explanation:
First we need the find the set of x such as 2x + 3 >= -3
2x + 3 >= -3 [Sum -3 in both sides]
2x + 3 - 3 >= - 3 - 3
2x >= -6 [Now, divide both sides by 2]
2x / 2 >= -6/2
x >= - 3
So, for every x>= -3 we have that 2x + 3 >= -3
Now we do the same with the other ineq:
5x-2 < 3 [sum 2 in both sides]
5x - 2 + 2 < 3 + 2
5x < 5 [divide by 5 in both sides]
5x / 5 < 5 / 5
x < 1
So, for every x<1 we have 5x-2<3
Then our set it the intersection of both of the previous sects, it is:
(x<1)intersect(x>=-3):
Solution: -3 =< x < 1
27-16 =11
11-4=7
7 is the remaining pizzas of sausage
We don't have to stress too much over the details, which are a little muddled here. When we scale the linear dimension by a factor of <em>f </em>we scale areas by a factor of .
It's not totally clear from the question but let's say A is on the inner circle of radius <em>r</em> and B on the outer circle of radius <em>R.</em> The linear dimensions are scaled by the ratio so the area is scaled by
Answer:
Answer:
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.
Step-by-step explanation:
Lin runs 5 laps around a track in 10 minutes.
i.e. 5 laps in 10 minutes.
so
5/10 = 1/2 laps per minute
- unit rate = 0.5 laps / per minute
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
Unit rate = 0.5 laps per minute
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.
